[PATCH v4 0/4] clk: rockchip: support clk controller for rk3328 SoC

[Elaine Zhang]

Changes in v4:
  dropping the "rockchip,cru" and "syscon" properties for bindings of rk3328
  adjust the pacth 3 and 4 order.
  move pll_rk3328 to patch 3.
Changes in v3:
  fix up the pll type pll_rk3328 description and use.
Changes in v2:
  add bindings for rk3328 clock controller

Elaine Zhang (4):
  clk: rockchip: add dt-binding header for rk3328
  dt-bindings: add bindings for rk3328 clock controller
  clk: rockchip: add new pll-type for rk3328
  clk: rockchip: add clock controller for rk3328

[PATCH v4 1/4] clk: rockchip: add dt-binding header for rk3328

[Elaine Zhang]

Add the dt-bindings header for the rk3328, that gets shared between
the clock controller and the clock references in the dts.
Add softreset ID for rk3328.

[PATCH v4 2/4] dt-bindings: add bindings for rk3328 clock controller

[Elaine Zhang]

Add devicetree bindings for Rockchip cru which found on
Rockchip SoCs.

Changes in v4:
  dropping the "rockchip,cru" and "syscon" properties for bindings of rk3328

+* Rockchip RK3328 Clock and Reset Unit
+
+The RK3328 clock controller generates and supplies clock to various
+controllers within the SoC and also implements a reset controller for SoC
+peripherals.
+
+Required Properties:
+
+- compatible: should be "rockchip,rk3328-cru"
+- reg: physical base address of the controller and length of memory mapped
+  region.
+- #clock-cells: should be 1.
+- #reset-cells: should be 1.
+
+Optional Properties:
+
+- rockchip,grf: phandle to the syscon managing the "general register files"
+  If missing pll rates are not changeable, due to the missing pll lock status.
+
+Each clock is assigned an identifier and client nodes can use this identifier
+to specify the clock which they consume. All available clocks are defined as
+preprocessor macros in the dt-bindings/clock/rk3328-cru.h headers and can be
+used in device tree sources. Similar macros exist for the reset sources in
+these files.
+
+External clocks:
+
+There are several clocks that are generated outside the SoC. It is expected
+that they are defined using standard clock bindings with following
+clock-output-names:
+ - "xin24m" - crystal input - required,
+ - "clkin_i2s" - external I2S clock - optional,
+ - "gmac_clkin" - external GMAC clock - optional
+ - "phy_50m_out" - output clock of the pll in the mac phy
+
+Example: Clock controller node:
+
+	cru: clock-controller@ff440000 {
+		compatible = "rockchip,rk3328-cru";
+		reg = <0x0 0xff440000 0x0 0x1000>;
+		rockchip,grf = <&grf>;
+
+		#clock-cells = <1>;
+		#reset-cells = <1>;
+	};
+
+Example: UART controller node that consumes the clock generated by the clock
+  controller:
+
+	uart0: serial@ff120000 {
+		compatible = "snps,dw-apb-uart";
+		reg = <0xff120000 0x100>;
+		interrupts = <GIC_SPI 56 IRQ_TYPE_LEVEL_HIGH>;
+		reg-shift = <2>;
+		reg-io-width = <4>;
+		clocks = <&cru SCLK_UART0>;
+	};

[PATCH v4 3/4] clk: rockchip: add new pll-type for rk3328

[Elaine Zhang]

The rk3328's pll and clock are similar with rk3036's,
it different with pll_mode_mask, the rk3328 soc
pll mode only one bit(rk3036 soc have two bits)
so these should be independent and separate from
the series of rk3328s.

Changes in v4:
  adjust the pacth 3 and 4 order.
  move pll_rk3328 to patch 3.
Changes in v3:
  fix up the pll type pll_rk3328 description and use

[PATCH v4 4/4] clk: rockchip: add clock controller for rk3328

[Elaine Zhang]

Add the clock tree definition for the new rk3328 SoC.

Changes in v4:
  adjust the pacth 3 and 4 order.
Changes in v3:
  fix up the pll parent only xin24m.
Changes in v2:
  fix up these *_sample error description.

looks good in general, I have some styling nitpicks below and would like
the grf-clocks solved differently, also explained below:

blank line between two comment blocks please.
Same for similar setups in the code above.

Please look at the other clock drivers for indentation. I.e. don't align with 
the "(", but instead use the same indent everywhere.

This makes things like the register address always sit in the same position
and thus makes it easier to read the clock diagram.

For the following long list of gates, just make it one line per gate and do 
not line-break them ... see other clock drivers for reference.

This long gate list is very uniform (= only gates) and reducing the number
of lines needed makes it easier to parse for those.

please drop this notifier and asorted code above for dumping cru registers.

We definitly don't want to bind against the regular GRF node. This causes a 
double mapping of the region and in general this isn't the clock-controller 
and just contains 2 clocks controls that somehow ended up in the GRF :-) .

Instead please take a look at the muxgrf clock patches I Cc'ed you on some 
minutes ago.

please move these to the armclk defintion in the controller driver
where already the other definitions are


Thanks
